Hazardous gases such as nitrogen dioxide (NO<sub>2</sub>) and particulate matter (PM) with aerodynamic dimensions of 10 µm (PM<sub>10</sub>), 2.5 µm (PM<sub>2.5</sub>) and 0.1 µm (PM<sub>0.1</sub>) are examples of air pollutants which can travel deep into the airways and alveolar regions of the lungs. Inhalation of PM and other gaseous pollutants induces oxidative stress and damage in the airway epithelium, resulting in activation of pro-inflammatory responses and attraction of immune cells. This review discusses the prevalence and consequences of air pollutants on respiratory illnesses, emphasizing the necessity for effective treatments. It also spotlights promising natural products and their derived compounds, which have demonstrated favourable pharmacological properties in managing oxidative stress and inflammation, crucial contributors to respiratory diseases, based on a thorough analysis of existing literature. Among these, marine algae have emerged as a particularly rich source of bioactive compounds including sulfated polysaccharides, phlorotannins, carotenoids, and sterols that exhibit potent antioxidant, anti-inflammatory, and immunomodulatory effects.

Despite the availability of many methods, including systematic evolution of ligands by exponential enrichment, there is no reliable method that can address aptamer-target binding energetics during aptamer design. We have developed a technique to do so, combining theoretical and computational methods. In this energy-based method, we calculate drug-target binding energies (DTBEs) and monitor phenomenological drug-target binding energetics related to drug-target association/dissociation processes, considering screened Coulomb interactions (SCIs) among a distribution of functional charges in a complex of an aptamer or aptamer building block (ABB) and target biomolecule in the biological environment where interactions take place. An ABB is any nucleotide: adenine, guanine, cytosine, uracil (for RNA), or thymine (for DNA). We have designed a set of novel aptamers for phosphatidylcholine, an important biomolecule relevant to various therapeutics, that are outlined here. In summary, our drug designing method involves constructing an aptamer using a seed-and-grow approach, optimizing SCIs, and selecting aptamer length based on the trend of DTBE in an aqueous environment, where aptamers interact with target(s). This novel technique, the screened Coulomb interaction approach (SCIA), ensures the discovery of target-specific aptamers as the target specificity is inherently incorporated during the aptamer design phases. SCIA is expected to significantly enhance aptamer discovery research and help develop aptamer-based therapeutics for diseases where specific drug targets are known.</div></div>","PeriodicalId":33528,"journal":{"name":"Medicine in Drug Discovery","volume":"29 ","pages":"Article 100247"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
